The aim of this script is to analyse the usage of EAGLE vocabularies in the Epigraphic Database Heidelberg as part of the FAIR Epigraphy project and the Epigraphy.info working group tasked with cleaning up the EAGLE vocabularies.

0.1 Environment setup

library(tidyverse)
library(jsonlite)

0.2 Loading data

Load the EDH dataset

If you have a locally saved dataset

EDH <- fromJSON("./data/EDH_text_cleaned_2021-01-21.json") ## 2021 version
head(EDH)

You can download the latest dataset directly from Zenodo (uncomment and run the appropriate version). !!!The structure of the data might have changed in between versions as the EDH changed its structure in 2021. This script has been written with the data from 2021 and the code might need minor edits with the data from 2022!!!

### 2021 version
# EDH <- jsonlite::fromJSON("https://zenodo.org/record/4888168/files/EDH_text_cleaned_2021-01-21.json?download=1")

### 2022 version 
# EDH <- jsonlite::fromJSON("https://zenodo.org/record/7303886/files/EDH_text_cleaned_2022-11-03.json?download=1")

If you are interested in how this dataset was compiled from the EDH API and XML data dumps, see the Github repository: https://github.com/sdam-au/EDH_ETL.

1 EAGLE vocabularies

EAGLE_vocabs<- read.csv("data/queryResults.csv", sep = ",")
head(EAGLE_vocabs)

EAGLE_typeins<- read.csv("data/EAGLE_typeins_all.csv", sep = ",")
head(EAGLE_typeins)

2 Use of EAGLE vocabularies in the EDH

The Epigraphic Database Heidelberg (https://edh-www.adw.uni-heidelberg.de/) uses the existing vocabularies from EAGLE Project (https://www.eagle-network.eu/resources/vocabularies/) in the following five Epidoc XML tags: Object Type, Keywords, Material, RS Execution, RS Decoration.

Example of record in XML:

<support>
  <objectType ref="http://www.eagle-network.eu/voc/objtyp/lod/257">Tafel</objectType>
</support>

In our processed version of the EDH dataset, all records consist of the following attributes:

Eagle Linked Open Data numeric code for vocabulary, i.e. 257, extracted from the reference within the Epidoc XML tag.
Free text description, extracted from the XML tag.

See the raw data below:

EDH_eagle<- EDH %>% 
  select(layout_execution, layout_execution_text, support_objecttype, support_objecttype_text, support_material, support_material_text, support_decoration, keywords_term, keywords_term_text, type_of_inscription_clean)

EDH_eagle

2.1 Inscriptions with missing data from XML files

In 2021, the total of 346 record were missing information extracted from XML files (due to delay in availability of published data through EDH data dumps on their website). However, at least partial information about them could be extracted from the then existing EDH API. For the purpose of the current evaluation of the Eagle vocabularies are these 346 records considered as missing as we cannot access their respective XML files with vocabularies.

EDH %>% 
  filter(is.na(support_objecttype)) -> missingXML
missingXML

2.2 The total number of Eagle vocabularies in EDH dataset

#object
EDH_eagle %>% 
  filter(!is.na(support_objecttype) & support_objecttype != "") %>% nrow() -> object_total

#type inscription
EDH_eagle %>% 
  filter(!is.na(keywords_term) & keywords_term != "" ) %>% nrow() -> typeinsc_total

#material
EDH_eagle %>% 
  filter(!is.na(support_material) & support_material != "") %>% nrow() -> material_total

#writing
EDH_eagle %>% 
  filter(!is.na(layout_execution) & layout_execution != "") %>% nrow() -> writing_total

#decoration
EDH_eagle %>% 
  filter(!is.na(support_decoration) & support_decoration != "") %>% nrow() -> decor_total


#how many Eagle vocabularies has been used in the EDH
Eagle_total <- object_total + typeinsc_total + material_total + writing_total + decor_total
